Versatile properties for accurate analyses
This cuvette is suitable for a wide range of analytical applications in biotechnology, chemistry, and industrial laboratory environments. Its design not only allows simultaneous monitoring of color changes and concentrations, but also smooth transitions during reactions. Its resistance to numerous chemicals ensures that it remains reliable even in demanding media. In combination with common spectrometers or photometers, it ensures reproducible results and a short training period. The following features are particularly noteworthy:
- Special optical glass (OS) for the range 320 nm to 2500 nm
- Layer thickness: 10 mm for reliable absorption standards
- Center height: 8.5 mm, ideally matched to many common measuring systems
- Two practical screw connections (M 6 x 1) for secure flow
- Volume of 80 µl for samples with low material requirements
- FEP tubing (outer diameter 1.9 mm, inner diameter 1.1 mm)
- Robust external dimensions (35 x 12.5 x 12.5 mm) with an aperture diameter of 3 mm
Equipped with two windows, the cuvette enables optimal light transmission and reliable detection even at low substance concentrations. Since its housing is also designed for increased flow rates, important parameters such as flow intensity remain constant within narrow limits, further increasing accuracy. In addition, the special optical glass meets the high requirements of laboratories that regularly work in the UV range or want to measure samples in the visible to near-infrared range.

Manufactured in accordance with current laboratory standards and featuring a robust design, it delivers reliable results even under changing environmental conditions. Whether for routine checks or in research-oriented laboratories, this cuvette provides the accuracy needed to achieve insightful and reproducible results.
FAQs
What is the best way to clean the cuvette?
For thorough cleaning, use a rinsing solution or a mild, laboratory-grade cleaning agent, depending on the medium. Finally, the cuvette can be rinsed with distilled water or a suitable organic solvent and left to air dry.
Can I use aggressive chemicals?
The special optical glass is highly resistant to many acids and bases. Nevertheless, strongly oxidizing substances or extremely alkaline solutions should be tested in advance to avoid possible surface damage.
What flow rates are recommended?
Flow rates vary depending on the viscosity and type of sample. In general, moderate rates are suitable to ensure stable and consistent measurement. For accurate results, it is recommended to adjust the pump output to the viscosity used.
How can I avoid measurement errors at low concentrations?
For very low concentrations, it is advisable to ensure the correct layer thickness and to clean the cuvette thoroughly on a regular basis. Adjusting the measurement parameters (e.g., extending the measurement time) can also increase accuracy.
Conclusion
This robust compact cuvette combines high optical purity with a precise flow design, contributing to valid, reproducible measurement results in a wide range of laboratory environments. Its practical design with two screw connections and the use of resistant materials such as special optical glass and FEP tubing make it ideal for automated processes, continuous sample feeding, and close-meshed absorption measurements. Professional users looking for a reliable and durable solution for photometric and flow applications in areas such as biotechnology, the food industry, or environmental analysis benefit from precisely scalable results and intuitive handling.
